Abu Huraira reported Allah's Apostle (ﷺ) as saying:Let him be humbled into dust; let him be humbled into dust. It was said: Allah's Messenger, who is he? He said: He who sees either of his parents during their old age or he sees both of them, but he does not enter Paradise.
حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " رَغِمَ أَنْفُ ثُمَّ رَغِمَ أَنْفُ ثُمَّ رَغِمَ أَنْفُ " . قِيلَ مَنْ يَا رَسُولَ اللَّهِ قَالَ " مَنْ أَدْرَكَ أَبَوَيْهِ عِنْدَ الْكِبَرِ أَحَدَهُمَا أَوْ كِلَيْهِمَا فَلَمْ يَدْخُلِ الْجَنَّةَ " .
